SPECIFICATION forming part of Letters Patent No. 380,730, dated April 10,1888.

Application filed August I, 1887. Serial No. 245,768. (No model.)

To all whom it may concern.-

Be it known that I, J OAOHIM SOHILDHAUER, of New Holstein, in the county of Calumet and State of Wisconsin,have invented new and useful Improvements in Villow-BarkStripping Machines; andIdo hereby declarethe follow ing to bea full, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the letters or figarcs of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a device for stripping the bark from basket-willow or willow boughs which are used in the manufacture of baskets and other willow ware.

The construction of my invention is explained by reference to the accompanying drawings, in which Figure 1 represents an end view, and Fig. 2 represents a side viewthereof.

Like parts are represented by the same reference-letters in both views.

A is a substantial bench, which serves as a seat for the operator when stripping the willows. The bench A is provided on its respective sides with levers B and O, which are pivoted to the rear end,D,of the bench upon bolts or screws E E. The front ends of the levers B and C are supported upon the two-armed lever F. To the front end of the bench A is a rigidly affixed standard, G, which serves to support the stripping-blades.

The bark is stripped from the willows by two stationary blades, H H,Which are rigidly affixed to the standard G by screws I I I, and by the two movable blades J J, which blades J J are pivoted at their lower ends to the standard G upon screws K K. The movable blades J J are connected with the operatinglevers'B and 0, through the pivotal bolts L L, links or rods M M, pivotal bolt N, and said two-armed lever F. The two-armed lever F is pivoted to the front end,O, of the bench upon the pivotal bolt P. Motion is communicated to the levers B and O by the feet of the operator, and from thence through the mechanism described to the movable blades J J. Thus it is obvious that by applying a downward pressme upon the lever 0 the short arm a of the lever F is thrown downward and the long arm I) of thelever Fis thrown upward, carrying with it the links M M, whereby the upper ends of the stripping-blades J J are thrown apart and separated from each other, whereby the operator may readily insert the willow to be stripped between the stripping-edges of said blades J J and the stripping-edges of the sta tionary blades H H, when, by a downward .pressure upon the opposite lever B, the long arm of said lever F is forced down ward,whereby said movable blades J J are, through the connecting-links M M, drawn downward firmly upon the exterior surface of the willow. Thus the willow is grasped, as is shown in Fig. 1, upon four sides between the stripping-edges of said blades,\vhereby, as the willow is drawn rearward by the operator, the bark is speedily removed from the bough, and as the smaller end of said bongh is drawn between said blades said blades J J are drawn closer together and in closer proximity to said stationary blades by the continuous downward pressure of the operator upon said lever B,whereby a continuous uniform pressure of the blades is applied throughout the entirelength of the bough from its larger to its smaller end, and whereby all the bark is readily and nicely stripped from the willow, when, by a downward pressure upon the lever C, said movable blades J are again thrown apart for the reception of another willow, as stated. Thus it is obvious that by pressing downward upon said levers B and G alternately said stripping-blades J J are opened and closed for the reception of and operation upon the willows.

Having thus described my iuvention,whatI claim as new, and desire to secure by Letters Patent, is-

1. In a barkstripping machine, the combination of a bench, A, operating-levers B and O, pivoted at their rear ends to the rear end of said bench A, and resting at their front ends upon the two-armed lever F, two-armed lever F, pivoted to the front end of said bench at right angles to said levers B and O, stationary stripping-blades H H,rigidly affixed to an upward-projecting standard at the front end of said bench A, movable blades JJ, pivoted at one end to said upward-projecting standard and connected at their free ends with said twoarmed leverFby the eonnecting'links or rods M M, and connecting links or rods M M, pivoted at their lower ends to said lever F and at their upper ends-to said movable blades J J, all substantially as and for the purpose specified.

2. The combination of the bench A, pro vided at its front end with the stationary vertical standard G, stationary vertical standard G, stationary blades H H, rigidly affixed to said standard G, movable blades J J, pivoted to said standard G on the respective outward sides of said blades H H, connecting links M M, pivoted at their upper ends to said blades J J upon pins L L, and at their lower ends to the twoarmed lever F upon a single pivotal bolt, N, pivotal bolt N, two-armed lever F, secured at one side of its center to the front end of said stationary frameupon pivot P, pivot P,and leversBand C,

located,respectively,upon the respective sides of the bench A and pivoted at their rear ends to the rear end of said bench A, bearing at their front ends upon the lever F, respectively,upon the respective sides of the pivot P, whereby, by the downward pressure of the lever 0, said movable blades are separated,while by the downward pressure upon said lever B 25 they are drawn together, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOACHIM SOHILDHAUER.
